A surfactant (soap or other cleaning agent) is the chemical compound that does the job. The type of cleaning agent used is the key to how well the job is done. Effectiveness, lack of residue, toxicity etc. are some of the considerations in choosing the brand. ROR, the most popular uses ammonia as its active ingredient. Zeiss uses alcohol. I have no idea if either of these hold other ingredients. ClearSight is a concoction of three active ingredients plus other additives listed in http://www.thegrid.net/joecodi/clearsight.html Since you seem to be a skeptic, send me your address and I will send you a sample. You can decide for yourself if it is as good as many LUGers have discovered. As for a cloth, if you do not have well used shorts, I'll send you an official lens cleaning cloth.
